1971BB427 I'd say you HAVE figured out the problem and corrected it. Often times a small piece of debris will lodge in the seat, and the only way it will dilodge is through the method you used. With a good filter ahead of the carb it shouldn't be a future issue.

trees I suggest you figure out your problem and correct it with out a hammer. You are asking for a serious engine fire.

RayCharles update:
my fuel inlet threads, the thing that houses the filter, are mashed up. Someone before me put in quite a big of epoxy. I cleaned it out and screwed it back together carefully.
I was still having the fuel overflow problem. My friend suggested hitting the area over the needle with a hammer while the carb was sitting on the car. Tapped if a few times with a hammer and that must've unstuck the needle because it stopped gushing gas all over the place. He said that he used to have to do it all the time on his 70 Falcon. He'd pull over and tap his carb a few times with a hammer and then be on his way. He had another hammer trick for his starter too. Anyway, thanks for the help.

RayCharles I took the carb back apart. I measured the float. It was dead on. I checked the needle. It was fine.
I should mention that the man I bought the car from had had the carb rebuilt.
I drive this Firebird every week.

I reinstalled the carb. I started it up. It was running fine. I cut the choke with tap of the peddle. The RPM's didn't drop to 400 so I was thinking I fixed the vaccum leak. I was patting myself on the back and then gas started coming out the top again.

I am thinking that there is something obstructing the needle from being able to seat correctly. I am having a heck of time trying to get the fuel filter thing to come off.

1971BB427 One of three things.
Float level too high
Something stuck in the needle
Too much fuel pressure to carb

Has the car been sitting for any length of time? If so, it may have crud in the fuel lines and after rebuilding it the carb may have gotten more crud on start up and plugged the needle again. Had this happen on one that I rebuilt on a car that sat for 10 yrs.
Pull it apart and recheck everything, then make sure you've got a good filter ahead of the carb.

You probably have something in the needle/seat or the floats are way off. JMO What carb is it you are working on ?
Go back and re-check the floats and make sure you got everything clean so that nothing is blocking the needle valve. JMO Simply re-check your work.
You should have verified where the vaccum leak was first IMHO.
